i just hope that they won't expand the tram any further west of stapleford
Hmm, Why?
If as I suspect the East Mids HS2 station is on part of the Toton Sidings site, there would be a strong business case to extend NET the mile or so down the hill from Bardills roundabout (the 'Toton park and ride' terminus about to be built) to the HS station. This would be a low cost option to achieve dispersal from the HS2 station into many parts of Greater Nottingham, and would reduce the numer of local rail services to be re-routed through Toton.
(obviously I'm indulging in wild speculation here).
Once you've got the NET to Toton sidings you may as well extend to Long Eaton Town Centre with another branch to Stapleford town centre, since both are also within a stones throw. I get the impression Stapleford could use the investment.
As for a business case for extending into residential areas beyond Long Eaton and Stapleford town centres, I really dont know.
Also going further west than Phase 2 would need to be funded differently, as you couldn't justify using Nottingham parking levy money for work in Derbyshire (in the case of Long Eaton).
